The square base Promaseal retrofit fire collars are multi purpose collars designed for us with concrete/masonry floors or walls, lightweight partitions and lined ceilings. These split collars can be retrofitted where necessary. They are available in a range of sizes to suit plastic pipes up to 315mm OD. Square based Promaseal retrofit collars above 200mm outside diameter have a circular base instead.
The round base retrofit collar are designed to be fitted around installed pipes that pass through floors and have been tested with ABS, HDPE and uPVC pipes up to 100mm outside diameter. Circular based Promaseal should be unclipped, placed around the pipe, reclipped and pushed tight to the floor.
The collars have been tested up to 240 minute fire resistance in accordance with the criteria of AS/NZS 1530.4 and AS 4702.1 with various types and sizes of plastic pipes in floors. For HDPE pipes the circular collars have been tested for up to 180 minutes in walls.
